"It's just a job and work. Throw the term 'serve' in the bin. It's part of the fetishism of war and violence."
Later, she wrote that it was a "hilarious notion" that our Diggers fought for our right to free speech and that "Australians who have worked in the violence industry have fought wars to suck up to the US and British".
On Tuesday, a former soldier wrote to Deveny: "Catherine, I served my country, as a soldier, for 26 years. How many did you serve? Zero."
The comedian responded: "You didn't serve your country, you chose a job in the violence industry."
She finished with a third tweet late on Tuesday night: "ANZAC Day. It's Bogan Halloween."
Deveny has been here before. She is an outspoken critic of Anzac Day and previously wrote that she expects the "yearly hate explosion over my Anzac Day opinions".
"My views, that Anzac Day does not reflect the inclusiveness of all those affected by war, nor our more sophisticated understanding of the true machinations and motivations behind war are neight rare, radical or new."
In recent years, she wrote: "Anzac Day. A celebration of a society so f***ed up it saw no other option than to go to war. Kill, rape and invade. Then glorify it."
The response is almost always the same. Some support her, many are disappointed.
"It must be that time of the year again," Guy McRedmond wrote on Twitter.
"When you try to convince yourself that you are somehow relevant by tweeting more uneducated rubbish about ANZAC Day and serving members of the ADF. It's easy to post crap to get a reaction. Certainly a lot easier than serving one's country."
Another wrote that Deveny has "the right to free speech but this is vulgar. Would you say that to the face of an elderly soldier?"
But others respond with threats of rape and violence and ruin any chance for sensible debate.
After a series of tweets in the lead up to Anzac Day this year, Deveny wrote that Anzac "trolls" are "ignorant and uneducated and prove my point better than I ever could ... Show Some Respect = Shut The F*** Up Or I'll Threaten To Rape You".
She's not the first Australian with a profile to speak out against Anzac Day. Former SBS presenter Scott McIntyre was sacked in 2015 after referring to Australians marking Anzac Day as "poorly-read, largely white, nationalist drinkers and gamblers".
The Prime Minister Malcolm Turnbull responded on Twitter, saying it is "difficult to think of more offensive or inappropriate comments" and that the "despicable remarks deserve to be condemned".
That didn't stop him from posting a bunch more tweets on the subject in 2016.
